I use the following commands:
Code:nvram set clkfrq=1000,800 nvram commit && reboot
After the reboot
Code:nvram get clkfrq
Shows 1000,800
But BogoMIPS still shows near 1595
I've tried 1000,666 or 1000,533, and still no joy.
If I use your turbo mode the BogoMIPS jump to near 2000, which I would assume means the CPU did increase.
If I now try 1200,666 or 1200,800, the BogoMIPS remain at 2000.
If I turn off turbo mode by simply pressing the LED button and try the commands again with either 1000 or 1200, the BogoMIPS remains at 1600.
I must be doing something wrong. I've tried the commands in the GUI, and also via telnet.

Newer bootloaders don't seem to support overclocking, so it's possible that yours shipped with such a bootloader. What version does it show under Tools -> Sysinfo? 1.0.1.6 (and possibly newer ones too, tho not confirmed) won't work.
